CarharttMen's Loose Fit Midweight Full-Zip Sweatshirt

How much does it weigh?

My husband is 6’8 “ do you think it will fit ?

My husband is 250 and 5'10. He usually wears an x-large hoodie. The size chart says that's what he would wear in this. Would an X-L fit him?

Is the hood functional? That is, can you pull it over a hat for protection from the weather?
